Effects of baryon resonances on nucleon-nucleon interactions in a quark model

摘要

Nucleon-nucleon S-wave scattering is studied by using the resonating group method, which includes not only the nucleon and Delta but also their excited states. As quark-quark interactions, the one-gluon-exchange and one-pion-exchange potentials are employed with phenomenological confinement potential. Compared with the N and Delta, coupling effects induced by excited-state baryons are small. (C) 2000 Published by Elsevier Science B.V. All rights reserved. [References: 25]
